What’s this?

This month, Akaieric wants you to scratch your heads with the picture of the month. He chose the theme “What’s this?” (Mais qu’est-ce que c’est?), indicating:

The idea is to find a mysterious picture, representing who knows what, so that the reader, upon viewing it, won’t be able to say anything other than “But… what’s this?”. Up to you whether you choose to explain, or not, what’s behind the mystery…

So here you go, my mystery picture. Will you figure out what it is, and what it’s for? It took me a couple of years after seeing one, before discovering the purpose of this strange thing. Try guessing in the comments, and I’ll give the answer in my next post 🙂

A sort of mailbox for hikers, if you open it up, you’ll find scraps or paper or a notebook and a pen or pencil to write the date and your names. The snazziest one I ever say included some first aid supplies too!

Almost there, but not quite. Not for hikers :D. I recall saying log boxes at the entrance of hiking trails on the Yellowstone National Park. The rangers wanted people to log their start/end time of the trail, so that they can go look for lost hikers at the end of the day…
